An air separator can be coupled with the ultrafine material crusher system to remove the proper sized (minus 325 Mesh or 45μ) material with each pass of the raw material through the ultrafine material crusher system. Removal of the fine particulate with each pass can make the crushing of the remainder of the raw material much more efficient.

The raw material to be crushed can be 96 percent particulates larger than 325 M or 38μ, 72 percent particulates larger than or equal to 200 M, 6 percent particulates larger than 100 M, and 1 percent particulates larger than or equal to 70 M.
The raw material can be crushed in a single pass through the ultrafine material crusher system at three thousand revolutions per minute.
The resulting material, or finished product, can be 100 percent particulate of minus 100 M, 68 percent particulate of smaller or equal to 200 M, and 21 percent particulate of smaller or equal to 400 M.
